大运河国家文化公园项目空间分布特征及其影响因素

Spatial distribution characteristics of the Grand Canal National Cultural Park project and its influencing factors

重大项目是建好用好国家文化公园的关键,也是集中打造中华文化重要标志的核心承载。本研究侧重于当前国家文化公园研究中较少关注的重要项目研究视角,运用数理统计与GIS空间分析方法分析其空间分布特征,并结合地理探测技术分析空间分布的影响因素。结果表明:(1)大运河国家文化公园重大项目呈现点轴状分布特征,80%以上分布在运河10 km缓冲区内。(2)项目空间分布呈现“核心集聚,相连成片,带状分布”的特点,包括天津市高密度集中区,安徽江苏两省西南交界次密度核心区以及天津市河北区-山东省济宁市任城区、河南省濮阳市南乐县-河南省洛阳市瀍河回族区、安徽省宿州市埇桥区-浙江省嘉兴市秀洲区3条带状分布区。(3)项目空间分布受多重因素影响,各影响因素解释力排名为:运河文化遗产邻近度>第三产业比重>运河水系邻近度>政策支持力度>交通道路邻近度>财政收入水平>常住人口规模。不同影响因素的交互影响力均大于单项影响因素,运河文化遗产邻近度与第三产业比重的交互作用最强。本研究从空间视角研究重大项目,探索了国家文化公园项目的整体空间布局以及项目遴选的空间因素,深化了目前巨型线性文化遗产管理的项目制研究,对优化国家文化公园项目整体格局,促进协调发展具有重要意义。

Major projects are the key to building and utilizing National Cultural Park well,and also the core carrier of building important symbols of Chinese culture.This paper focuses on the perspective of major projects that are less concerned in the current study of National Cultural Park,analyzes their spatial distribution characteristics by using mathematical statistics and GIS spatial analysis methods,and examines the influencing factors of spatial distribution in combination with Geodetector.The results show that:(1)Major projects of the Grand Canal National Cultural Park show the characteristics of point-axis distribution,with over 80%within the 10 kilometer buffer zone of the canal.(2)The spatial distribution of the project shows the characteristics of“core agglomeration,connected into areas,and belt-shaped distribution”,including the high-density concentration area in Tianjin,the sub-density core area at the southwest border of Anhui and Jiangsu provinces,and three banded distribution areas,namely Hebei District,Tianjin—Rencheng District,Jining City,Shandong Province,Nanle County,Puyang City,Henan Province—Chanhe Hui District,Luoyang City,Henan Province—Yongqiao District,Suzhou City,Anhui Province—Xiuzhou District,Jiaxing City,Zhejiang Province.(3)The spatial distribution of the projects is affected by multiple factors,and the explanatory power is ranked as follows:the proximity of canal cultural heritage the proportion of tertiary industry the proximity of canal water system policy support the proximity of traffic roads the level of fiscal revenue resident population scale.The interactive influence of different influencing factors is greater than that of single influencing factor,and the interaction between the proximity of canal cultural heritage and the proportion of tertiary industry is the strongest.This paper studies major projects from a spatial perspective,exploring the overall spatial layout of National Cultural Park projects and the spatial factors involved in project selection.It deepens the current research on the project system of giant linear cultural heritage management,which is of great significance for optimizing the overall layout of national cultural park projects and promoting coordinated development.
